THIS PROPOSAL IS PREPARED IN DIRECT RESPONSE TO THE NRC'S SOLICITATION FOR AN IMPROVED DEVICE TO MEASURE AIR MOVEMENT FOR PERSONNEL RADIATION PROTECTION AND HEALTH PHYSICS APPLICATIONS IN NUCLEAR FACILITIES. THE PURPOSE OF THE NEW DEVICE IS TO PROPERLY LOCATE AIR SAMPLERS SO THAT THE AIR SAMPLED IS REPRESENTATIVE OF THE AIR INHALED BY WORKERS. ALTHOUGH AIR FLOW RATE SENSORS SUCH AS ANEMOMETERS ARE ...

The nuclear weapons community has traditionally focused on the next generation or level of weapon capability complimented by gathering and analysis of actual test data. Now, with the cessation of actual weapons testing, there is an increased need to use the actual test data in modeling techniques to better understand the phenomenology and potential effects of nuclear weapons. The first phase of ...

Turbulence of gas flows by its very nature is one of the most difficult things to model and measure. We propose to develop a new way of measuring the turbulence and to compare these measurements to predictions using the k-epsilon model. Typical measurements, in the past, use smoke, Schlierin or shadow graph techniques to visually infer turbulence characteristics. These features are either motio ...

The magnetic field distribution in a Z-pinch, can be used to infer the currentsflowing in the pinch and study the stability during the implosion phase. Faradayrotation techniques are too insensitive for measurements during the run-in phase.Similarly, it is difficult to infer the Zeeman splitting from spectrally resolvedline profile when the splitting is much less than the absorption line width d.H ...

Survival of present day microelectronic circuits depends on their protection from self generated and external electromagnetic interference. This proposal is oriented toward the class of interference generally referred to as overvoltage transients. Means for mitigating these transients include gas discharge tubes, and various solid state devices. Each of these has their own advantages in particu ...

The Ktech Team proposes a feasibility study of a fuel/air driven flux compression power unit (FCPU) for electric guns. Through variations of inductance gradients and through changes in scale, the proposed technology will be applicable to both electrothermal/chemical and electromagnetic guns. In the Phase 1 effort, we develop simulation models to predict the performance of the flux compression po ...

Science based assessments of the response of systems and material to hostile nuclear environments require detailed verified material response and failure criteria for confident results. Consequently there is a need for the development of experimentaltechniques to measure low pressure equation of state parameters accurately and economically using radiation simulators. The development of a soft x- ...

The measurement of the variation of fluence from a Plasma Radiating Source (PRS) with polar angle is critical to the definition of the stimuli acting on an effects experiment using PRS diagnostics because in general experiments and diagnostics view thesource from different angles. The polar angle fluence distribution is controlled by the opacity of the pinch, which is a sensitive function of pinc ...

Present reflex triode (RT) design performance is limited by debris shield response. The shield designs were derived empirically to satisfy specific experiment requirements. Optimizing the RT design will double target dose. Debris shield deformation definesthe closest permissible location of the test object and therefore determines the maximum dose achievable. The deformation of the debris shield c ...
